Archives par mot-clé : Warming Hiatus

Terrestrial ecosystems play a significant role in the global carbon cycle and offset a large fraction of anthropogenic CO2 emissions. The terrestrial carbon sink is increasing, yet the mechanisms responsible for its enhancement, and implications for the growth rate of atmospheric CO2, remain unclear.

Yes, plants are doing it better than any carbon tax and they do it for free… as long as we don’t cut them down. You’d think we’d learn by now that managing climate comes back to how we have mismanaged the planet’s forests.

A new paper has been published in the Analysis section of Nature called Reconciling controversies about the ‘global warming hiatus.’ It confirms that the ‘hiatus’ or ‘pause’ is real. It is also rather revealing.

It attempts to explain the ‘Pause’ by looking into what is known about climate variability. They say that four years after the release of the IPCC AR5 report, which contained much about the ‘hiatus’ it is time to see what can be learned.

One could be a little sarcastic in saying why would Nature devote seven of its desirable pages to an event that some vehemently say never existed and maintain its existence has been disproved long ago. Now, however, as the El Nino spike of the past few years levels off, analysing the ‘pause’ seems to be coming back into fashion.

Looking at data objectively, it is pretty clear that there is little relationship between weather/climate and the rising CO2 concentrations in the atmosphere, as the global warming pause between 1997-2016 shows –

Anyone who has studied the history of science knows that scientists are not immune to the non-rational dynamics of the herd.

This week’s March for Science is odd. Marches are usually held to defend something that’s in peril. Does anyone really think big science is in danger? The mere fact that the March was scheduled for Earth Day betrays what the event is really about: politics.

During the first decade of the twenty-first century, the Earth’s surface warmed more slowly than climate models simulated1. This surface-warming hiatus is attributed by some studies to model errors in external forcing2, 3, 4, while others point to heat rearrangements in the ocean5, 6, 7, 8, 9, 10 caused by internal variability, the timing of which cannot be predicted by the models1. However, observational analyses disagree about which ocean region is responsible11, 12, 13, 14, 15, 16
